What is the one China policy?

What is the one China policy? To break it down, the U.S. acknowledges China’s position that there is only one legitimate Chinese government, based in Beijing, and that Taiwan is part of China. Strategically, however, the U.S. has never officially recognized China’s claim to the islands or commented on what would happen if Taiwan is attacked. Also under the policy, the U.S. does not have diplomatic relations with Taiwan; however, the U.S. supplies them with military gear and keeps unofficial contacts there. NewsNation
